Sufficiently high pressure, in the range of 0 to 150 psi, is applied to uniformly infuse the polymeric binder throughout the mat through the interstices between the fibers. The compression means comprises a heated platen heated to a temperature above the softening point or melting point of the polymeric particles of the binder, but below the softening point of the synthetic fibers, thereby aiding penetration of the binder into the mat. do. In the case of a thermosetting binder, it solidifies upon cooling. On the other hand, in the case of thermoset binders, sufficient heat must be maintained to activate the functional monomer or crosslinking agent and cure the binder. In either case, it is necessary to maintain temperature first to obtain flowability and then to set or cure. The practical temperature is
About 120-160°C1 preferably about 130-140°
It is in the range of C. Practical times for compacting and heating the binder-impregnated mat range from about 10 to 30 seconds, preferably about 15 to 25 seconds. For example, a desirable compression cycle consists of compressing a mat impregnated with a Tg 70°C vinyl copolymer binder for 20 seconds at a pressure of 42 ps+ between a platen heated to 135°C.

It is removed from the compression means and cooled to room temperature. This compressed fibrous sheet has high porosity, yet exhibits an unexpectedly high tensile strength of at least 5 pounds per inch. Preferably, this strength is at least 10 lbs/strand, and most preferably at least 15 lbs/strand. The porosity of this compressed fibrous nonwoven sheet decreases as the weight ratio of binder solids to fiber mat increases. This porosity is usually at least 2.5 to 40 seconds, preferably 10 to 35 seconds. A preferred compaction process is a discontinuous sheet compaction process. However, it is also possible to carry out a continuous process in which a continuous mat is passed through a resin-impregnated bath, and the resin-impregnated mat is held between heating rollers and compressed.
